VALID 12Z WED OCT 14 2009 - 00Z FRI OCT 16 2009
RAIN AND SNOW ASSOCIATED WITH THE STRONG PACIFIC SYSTEM MOVING
ACROSS THE CASCADE RANGE AND THE SIERRA NEVADAS IS CREATING MESSY
TRAVEL CONDITIONS FOR THE MORNING COMMUTE. IT WILL CONTINUE TO
WREAK HAVOC ON COMMUTERS THROUGH THIS EVENING. MODERATE TO HEAVY
PRECIPITATION WILL CONTINUE TO FALL OUT WEST THROUGH THE MIDDLE OF
THE WEEK...BOLSTERED BY A SECOND SURGE OF MID-LEVEL ENERGY BEHIND
THE CURRENT FRONTAL SYSTEM...BRINGING ADDITIONAL MOISTURE TO AN
ALREADY WET WEST COAST.
THE SOUTHEASTERN U.S. HAS BEEN UNABLE TO CATCH A BREAK FROM THE
RAIN. AREAS OF HIGH PRESSURE IN THE GULF OF MEXICO AND NORTH OF
THE GREAT LAKES ARE ACTING AS BOOKENDS...KEEPING THE FRONT ACROSS
THE SOUTHEAST FROM MOVING OUT OF THE AREA. HOWEVER..THE SOUTHEAST
WILL FINALLY SEE SOME FRONTAL MOVEMENT ON WEDNESDAY EVENING...AS
THE LOW PRESSURE CENTER LOCATED OFF THE COAST OF THE CAROLINAS
BEGINS RAPIDLY DEEPENING. THIS WON'T BRING AN IMMEDIATE END TO THE
RAIN...BUT THIS MOVEMENT WILL BE THE BEGINNING OF AN EVENTUAL
SOUTHWARD PUSH THAT WILL ULTIMATELY LEAD TO SUNNY SKIES IN THE
NEAR FUTURE.
THE RAPIDLY DEEPENING LOW PRESSURE SYSTEM OFF THE EAST COAST OF
THE U.S. HAS THE POTENTIAL TO BRING SOME UNSEASONAL SNOW TO THE
MIDDLE ATLANTIC REGION. IT WILL CERTAINLY BRING MODERATE TO HEAVY
RAIN TO THE CENTRAL EAST COAST AS WE HEAD INTO THE AFTERNOON ON
THURSDAY. BELOW AVERAGE TEMPERATURES WILL BE FELT ACROSS THE
MIDDLE ATLANTIC STATES AND NEW YORK. THE POTENTIAL FOR SNOW...OR A
RAIN AND SNOW MIX...RESTS ALONG THE NEW YORK AND PENNSYLVANIA
STATE LINES FRIDAY EVENING.
